+PascalCase is variadic function which takes one Param rule i.e slice of strings and it returns input type string in pascal case form and rule helps to omit character you want to omit from string. By default special characters like "_", "-","."," " are treated like word separator and treated accordingly by default and you don't have to worry about it.
